Combined muscle-strengthening and aerobic activities provide greater reductions in all-cause, cardiovascular, and total cancer mortality than either activity alone or neither.
For the best protection against death and major diseases, combine muscle-strengthening exercises with aerobic exercise. This combination offers significantly greater benefits (40% lower all-cause mortality) than doing either one alone.
Combined muscle- strengthening and aerobic activities (versus none) were associated with a 40% lower risk of all- cause mortality (RR 0.60...), a 46% lower risk of CVD (RR 0.54...), and a 28% lower risk of total cancer mortality (RR 0.72...)
Why this rating
Certainty is 'very low' due to heterogeneity and study count, but the magnitude of benefit is large.
